QTextEdit + auto scroll

[jbpvr]

I have a QTextEdit displaying data that is being written to a log file( at the same time)

I would like for the new data that is being added to the QTextEdit to always be visible when
new data is coming, but currently you have to scroll to the data to see it. Is there a way to have it scroll down to the bottom of the page always when data is being inserted.

Thanks,

svn co https://qt-webdav.svn.sourceforge.net/svnroot/qt-webdav qt-webdav

Probably the simplest way is to call QTextEdit::ensureCursorVisible() after adding some text to the text edit. In case you don't have a cursor (for example when the widget is read only), you might try this combination instead:

QTextEdit *edit; // assuming this is your text edit
QScrollBar *sb = edit->verticalScrollBar();
sb->setValue(sb->maximum());

This should scroll the widget to the bottom...

DO:

pTextEdit->insertPlainText(strText);
QTextCursor c = pTextEdit->textCursor();
c.movePosition(QTextCursor::End);
pTextEdit->setTextCursor(c);

Hi!

I' have a same behaviour with QTextEdit (which contain html text). It has chat functions. I load a GUI inside my code, which allready has a QTextEdit and a alwaysOn vertical scrollbar.
How I could autoscroll it to the end?

Thanks.

Cheers.

Move the cursor to the end.

You mean with this example above?



pTextEdit->insertPlainText(strText);
QTextCursor c = pTextEdit->textCursor();
c.movePosition(QTextCursor::End);
pTextEdit->setTextCursor(c);

Cause i did this (with PyQt) and din't worked...

Cheers.

Did you call ensureCursorVisible?
